The Mineral Plus+ Calcite Cartridge System adds back in the essential minerals (calcium & magnesium) to your drinking and cooking water which are removed from RO systems and Ultra filtration systems.

What does the Calcite Post Cartridge do? back to top
When installed after an RO system, this cartridge adds beneficial and needed calcium and magnesium back into the water. RO systems remove nearly 99% of all minerals and anything else from the water. Adding this after your RO will help keep your water balanced and full of beneficial minerals.

Great system/great service

Bay Head was hit hard by Hurricane Sandy and the water systems are still being rebuilt, but in the interim there was too much emulsified sand & dirt in the water. Further, the water smelled like a YMCA swimming pool. After installation of the activated carbon system and its sediment filter, our water is as good as any bottled water. No smell. No sediment. Whenever I need additional filters or information, this company answers the phone with a knowledgable representative ready to help. All good!

Had plumber install system that was recommended by Pelican. Did a very good job, knew exactly what he was doing. Fair price and finished in a few hrs. So far very happy with system. Plumber was Chet Craig Plumbing in Ocala. Formally C&D.

Whole house filter

Replaced old salt water conditioner and 10 inch filter whole house filter and PC1000. Works well, with little if any noticeable difference in water pressure with 3 or 4 showers going at one time.

just over 5 months

It is a shame I could not upload a photo of the prefilter that I just replaced this morning in less than 20 minutes. Maybe 30 minutes from the time I shut the water off, released the pressure in the house, replaced the filter, installed the new one, cleaned up the mess, and turned the water back on. Back to the picture, it is rust red from the San Antonio city water and there are granular build-ups between the sections of the filter strings. Thanks Pelican Water system.

PC600 water filter

Love the system. Easy to install, compact for less space taken in the garage. Extremely easy to service when changing the sediment filters. ECO friendly carbon material swap out and durable tank for less landfill trash.

Excellent product

Since installed seen a big difference in the shower, dish washer and washing machine. My clothing seems to come out softer, dishes cleaner and my skin feels so much better when coming out of the shower. My biggest hope so far is the reduction of lime deposits on my fixtures and appliances.

Great water!

We love our Pelican system! We have had it for a few months and the water tastes wonderful! The shower leaves no water spots and we don't have that slimey feeling after showering with a salt water softener. Glass and silverware come out of the dishwasher without any spots (without any special dishwasher additives). Most of all I like drinking water that I KNOW is pure and chlorine free (today's municipal water is a scary thing).

best way to go

If you have a well or stream you are getting your water from a U.V setup is the best way to go. Even if your water test good you never know when it may go to bad water. Dumping water treatments down your well to get a good test is only a temporary fix. I am very happy with my pro 10 and the way I have it set up. Also very pleased with Pelican water systems for all the info they give us and the help to set the pro 10 up.

Great product and great service

I've had the carbon and softner combo for five years. I have been very satified with how effective the filter system is. Thank you, Mark, for helping me with ordering and explaining to me about the replacement media. Also, thank you for your patience with me!
